You can see the last 10 IP addresses and approximate locations that accessed your Gmail account.

If you got a warning about suspicious activity in your account, you might also see up to 3 additional IP addresses that have been labeled as suspicious.

There are a few reasons you may see multiple IP addresses or locations in your activity:

If you use POP or IMAP to read your mail on other services, like Apple Mail or Microsoft Outlook, this location information will be included, too.

If you use Mail Fetcher, a Google IP will show up because your messages are being fetched through a Google server.

If you use Gmail on a phone or tablet, your Internet service or mobile carrier's location may show up. This may be a location far from where you are. As long as the name of the carrier matches yours, this isn't unusual.
